SPECIFICATION forming part of Letters Patent No. 239,919, dated April12, 1881.

Vand useful Improvement in Corset-Steel Fastenings, of `which thefollowing description, in

t connection with the accompanying drawings,

is a specification.,

This invention in corset-steel fastenings is an improvement on thefastenin gs represented in United States Letters Patent No. 225,375, towhich reference may be had. In that patent the fastening is held inplace near the inner edge ofthesteel by the same rivets that secure theusual eye-piece to the steel. Such construction restricts the length ofthe spring part ofthe fastenin'g to the distance between the said rivetsand the inner end ot' the straight part of the studlreceivin g eye,andnecessitates a very thin or slight spring when sheet metal is used,it being in practice the best material, both for best work andappearance.

In this my invention I have made the laterally-moving stud-fastenin gspring quite long,

have bent or curved it near its shank, so as to permit it t6 have aneasy movement, and have fastened or xed the said shank in position nearthe outer edge of that member of the steel with which it is intended tomove.

In practice I have extended the eye-piece backward across` the steel, ornearly so, and have attached the shank of the curved spring thereto, theeye-piece serving as a rest for the flat under side of the spring.

To insure true horizontal movement of the fastening-spring, I haveprovided a guide for its outer or free end, the said` guide also holdingthe free end of the spring down in place. Ihave also provided theeye-piece with a stop to arrest the movement of the fastening-springtoward the center of the eye-piece and prevent the head of the headedstud of the opposing steel striking the under side of and lifting thefastening-spring as the stud is being inserted up through the eye.

Figure l represents, in plan view, two steels with one of mysteel-fastenin gs applied to hold the steels together; Fig. 2, a planview of the fastening unhooked from the headed stud; Fig.3', alongitudinal section on the line .fr fr,

Fig. 2; Fig. 4, a cross-section on the line yy Fig. 5, a modification ofmy invention, and Fig. 6 a top view of, an eye-piece with the springomitted. Referring to Figs. 1 and 2, the steels ay b and headed stud dareall as usual.

The eye-pico `wprovided with the usual round-ended stu( -reeiving eye 3,and attached to the steel by the rivets @has its end 2 extended backwardsubstantially to the outer side of the steel. The upper side of thiseyepiece is depressed or reduced along one edge to form a ree-ess, h,(see Fig. 6,) to receive the sheet-metal fastening-spring f, which has anose,n, to spring behind the stud d, as in Fig. l, and prevent the studfrom moving backward along the said slot into the enlarged part of theeye. This springf is extended along the eye-piece to its rear end, whenit is bent or curved, as at 5, and the shank 6 of the spring is thenattached `to theV rearwardly-extended part 2 of the eye-piece, either byrivets, as in Fig. 1, or by a dovetail-connection, as in Fig. 5. Thebend 5 permits the spring f to yield at a considerable distance from thenose n, which enables me to employ a strong spring, and one which maybeemployed with less liability ot' being broken. The free end of thespring is extended under the guide g, (shown as a small projection,) itpreventing that end from rising, and guiding the end of the spring inits lateral movements effected by the pressure of the stud d against thenose n.

At the rear of the nose the eye-piece is provided with a stop, 4, whichI- prefer to employ to limit the forward movement of the spring. 'lheouter portion of the said stop, being flush with the outer portion of.the spring f, and being interposed between it and the eye 3, forms ashield, so that the head of the stud d, when being inserted in the saideye 3, cannot strike the under side of and lift the spring f from theeyepiece.

I claiml. In a corset-steel fastening, the eye-piece provided With arecess, h, combined with the longspringf, bent or curved near the outeredge of the steel at 5 to permit the spring to yield at that point,substantially as described.
